Engineer's Note

This RDIMM, with ECC and registered signal technology, is engineered for server platforms handling virtualization, in-memory databases, and data-integrity-critical workloads where error correction and high signal stability under heavy load are mandatory. Its single-rank x4 organization allows efficient memory access and optimized performance in high-density deployments, while the CL17 latency ensures responsive data retrieval.

Technical Specs & Insights

1. ECC protection silently corrects single-bit errors, preserving data integrity for financial transactions and mission-critical databases that cannot tolerate silent corruption.
2. Registered buffering stabilizes high-capacity memory configurations, enabling denser server deployments without compromising electrical signal quality across fully populated DIMM slots.
3. Generous capacity per module supports higher virtual machine consolidation ratios, allowing more business workloads per physical host while maintaining responsive memory allocation.
4. Sustained memory bandwidth accelerates in-memory datasets and real-time analytics, reducing response latency for concurrent query streams under heavy enterprise workloads.
5. Single Rank x4 organization minimizes load on memory channels, improving power efficiency and thermal headroom in large-scale data center racks where every watt matters.

Why These Specs Matter

Evaluating the part number reveals a server-class DDR4 RDIMM. Its ECC circuitry silently corrects single-bit errors, which is vital in virtualized clusters—a flipped bit in one VM’s kernel memory can crash critical services. The registered design buffers command and address signals so you can populate all memory channels with multiple DIMMs without signal degradation, making it the backbone for dense virtualization hosts or Redis in-memory databases that require terabytes of stable, reliable capacity. The single-rank x4 configuration minimizes load on the memory bus, delivering lower latency and higher sustained bandwidth for chaotic, random-access patterns typical of OLTP databases; every millisecond saved in a transaction directly improves user experience. At 1.2V and 2400MT/s with a CL17 latency, this module balances performance with power efficiency, cutting operational cooling overhead in rack servers. Together, ECC protection, register buffering, single-rank x4 agility, and efficient speed/latency turn always-on workloads into resilient, cost-effective deployments.

Endurance & Reliability

General Virtualization
For general virtualization, balance density and cost by populating two 16 GB RDIMMs per memory channel on dual-socket servers—12 modules yield 192 GB, comfortably supporting 30–50 typical VMs. The registered ECC design ensures data integrity, and single-rank x4 organization reduces channel loading so you can add capacity later without sacrificing stability.

In-Memory Database
In-memory databases demand maximum capacity and predictable latency. Fill all channels with one 16 GB DIMM per channel (1DPC) to sustain 2400 MT/s, then add a second module per channel for 2DPC when scaling to hundreds of gigabytes. The CL17 latency and ECC protection help maintain transactional consistency under heavy write loads.

High-Performance Computing
HPC workloads are bandwidth-driven: install one 16 GB RDIMM per channel for the fastest memory speed while still providing 64–128 GB per node—ideal for simulation and modeling. The registered signal type supports large multi-socket configurations, and low-voltage 1.2 V operation reduces thermal overhead, letting compute racks run denser without throttling.
